[Abstract]:With the continuous development of underwater acoustic technology and electronic technology, the data storage system plays a more and more important role in the research of underwater acoustic technology and the development of underwater acoustic equipment, and the continuous development of underwater acoustic equipment also plays an important role in the volume of storage medium. Higher requirements for capacity and speed of data storage, practicability, stability and cost control of the storage system itself are put forward. In this paper, the data storage extension of vector array target detection system is designed. The goal is to realize the receiving and receiving of network data and the local storage of data. This design uses MityARM-1808 as the core board, constructs the embedded Linux operating system, uses the USB2.0 to gigabit network adapter to realize the receiving and receiving of the network data and realizes the storage of the data on the SATA hard disk. This paper completes the design and debugging of the data storage extension of the vector array target detection system. Firstly, according to the system requirements, the hardware circuit of the data storage extension based on MityARM-1808 is designed and completed, including schematic design and PCB making. The hardware circuit includes core board peripheral interface circuit, network communication module, serial port module, SATA hard disk storage module, SD card memory module and power supply module. Then each hardware module is debugged, and the network data receiving and transmitting and SATA hard disk storage program are written, and the receiving and forwarding of the network data through TCP and the hard disk storage are realized. Finally, the performance of the design is tested and verified, including network transmission performance and hard disk storage performance, which proves the feasibility and rationality of the design.
